Abstract (en)
An imaging system (10) according to this disclosure includes: an acquisition unit (11) configured to acquire an iris image captured by an iris imaging means for capturing an iris of a target person at a first angle of view or a whole image captured by a whole imaging means for capturing the target person at a second angle of view wider than the iris imaging means; an estimation unit (12) configured to estimate a three-dimensional position of a target person being included in the acquired whole image; a selection unit (13) configured to select a coordinate transformation matrix that transforms a three-dimensional position of the target person into two-dimensional coordinates at the first angle of view; a transformation unit (14) configured to transform coordinates of an eye of a target person being included in a whole image associated with the estimated three-dimensional position into two-dimensional coordinates at the first angle of view, based on the selected coordinate transformation matrix; and a setting unit (15) configured to set, based on the transformed coordinates of an eye of the target person, a parameter for capturing an iris of the target person by the iris imaging means.
